A Novel Color Image Encryption using DNA Code and Dual Memristor Hyperchaotic System

This work presents a modified hyperchaotic system based on two memristors with unique Lyapunov exponents, offering a unique method for image encryption. The main goals are to use dynamic analysis to evaluate the complexity and unpredictable nature of the proposed method and then apply it to image encryption. A strong color picture encryption system is developed by combining Deoxyribonucleic acid (DNA) sequences, logistic maps, and the memristive hyperchaotic system. Using an upgraded four-dimensional dual memristor-based hyperchaotic system with three Lyapunov exponents, logistic mapping, and DNA encoding are all integrated in this technique. This research carefully combines these three methods to solve current issues with picture encryption schemes. Security performance tests and simulations, which verify the efficiency of the proposed algorithm against different attacks, such as brute-force, statistical, entropy, differential, visual, and histogram attacks, preserve methodological rigor. Comparisons with traditional chaotic systems in image processing demonstrate how much better security the proposed method exhibits. Important rmdings show how DNA operations may be successfully integrated with the hyperchaotic memristive system to produce improved picture encryption capabilities. The program not only proves its efficacy in protecting picture data, but it also performs better than traditional methods. Applications like information security, encryption, and secure communication are all affected by these discoveries. The research highlights the algorithm’s resilience to many attacks, highlighting its potential as a significant advance in image encryption algorithms. The suggested method offers a feasible way to protect strict image data in a variety of real-world situations.
